A CMB Polarization Primer
Wayne Hu, Martin White
We present a pedagogical and phenomenological introduction to the study of cosmic microwave background (CMB) polarization to build intuition about the prospects and challenges faci…
Observational Constraints on Open Inflation Models
Martin White, Joe Silk
We discuss observational constraints on models of open inflation. Current data from large-scale structure and the cosmic microwave background prefer models with blue spectra and/or…
Distinguishing Causal Seeds from Inflation
Wayne Hu, David N. Spergel, Martin White
Causal seed models, such as cosmological defects, generically predict a distinctly different structure to the CMB power spectrum than inflation, due to the behavior of the perturba…
Cosmic Confusion and Structure Formation
Martin White
We present a re-analysis of the cosmic confusion hypothesis, elucidating the degree to which ``confusion'' can be expected to hold in a class of flat, adiabatic models. This allows…
Why Not Consider Closed Universes?
Martin White, Douglas Scott
We consider structure formation and CMB anisotropies in a closed universe, both with and without a cosmological constant. The CMB angular power spectrum and the matter transfer fun…
